Floating petroleum oil spills on the marine ecosystem are generally associated with an escalation of serious environmental problems. This research aimed to synthesis five water‐soluble anionic Gemini dispersants to minimize the effect of floating petroleum oil spills on the marine ecosystem. Referring to the spacer type, these dispersant are classified into two categories: the first category is the three acyl amine Gemini dispersants of N,N′‐ diacyl, (distearoyl‐, dipalmitoy‐, and dimyristoyl‐) N,N‐′ sodium 2‐hydroxy 3‐propane sulfonate propane 1,3 diamine, denoted S, P, and M, and the second category is two alkyl amine Gemini dispersants of N,N′dialkyl ‐(dicetyl‐, and dilauryl‐) N,N′‐sodium 2‐hydroxy 3‐propane sulfonate propane 1,3 diamine, denoted C and L. Fourier transform infrared and ¹H NMR spectroscopy, gel permeation chromatography, and elemental analysis were used to verify the chemical formula of the synthesized dispersants. The effectiveness of the synthesized dispersants was investigated as regards their dynamic interfacial tension, carbon–chain length, and hydrophilic–lipophilic balance. The dispersion efficiency of the synthesized dispersant was detected qualitatively and quantitatively using the screen test and Warren Spring Laboratory methods, respectively. Experimental outcomes showed that the maximum dispersion efficiency of 94.7 wt% was achieved by dispersant C at a dispersant\oil ratio of 1:20 at 25°C.

用于处理原油溢油污染的新型阴离子双子油分散剂的合成与评价

漂浮在海洋生态系统上的石油溢漏通常与严重的环境问题升级有关。这项研究旨在合成五种水溶性阴离子双子星座分散剂，以最大程度地减少石油溢漏物对海洋生态系统的影响。关于间隔物类型，这些分散剂可分为两类：第一类是N，N′-二酰基（二硬脂酰基，二棕榈油和二肉豆蔻油基）N，N ′′钠的三种酰基胺Gemini分散剂2 -羟基3-丙烷磺酸盐丙烷1,3二胺，表示为S，P和M，第二类为N，N '二烷基的两种烷基胺Gemini分散剂- （dicetyl-，和二月桂）N，Ñ '-sodium 2-羟基-3-丙烷磺酸酯丙烷-1,3-二胺，表示为C和L傅里叶变换红外和^1个H NMR光谱，凝胶渗透色谱法，和元素分析用于验证合成分散剂的化学式。研究了合成分散剂的动态界面张力，碳链长度和亲水亲脂平衡的有效性。分别使用筛选试验和沃伦·斯普林实验室方法定性和定量地检测合成的分散剂的分散效率。实验结果表明，在25°C时，分散剂C在分散剂/油比为1:20的情况下可实现94.7 wt％的最大分散效率。
